SAFETY-PIN.

SPECIFICATION forming part of Letters Patent No. 777,409, dated.December 13, 1904.

Application filed December 15, 1902. Serial No. 135,222. (No model.)

To all whom, it may concern:

Be it known that I, FILIPA. FORSBECK, a citizen of the United States,residing at Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements inSafety-Pins, of which the following is a specification, reference beinghad to the accompanying drawings, forming a part thereof.

The main object of this invention is to facilitate engaging the point ofthe pin with the guard, or locking the pin, and disengaging the pointfrom the guard, or unlocking the pin.

It consists in certain novel features of construction and in thearrangement and combinations of parts hereinafter particularlydescribed, and pointed out in the claims.

In the accompanying drawings like letters designate the same parts inthe several figures.

Figure 1 is a side view of a safety-pin embodying the aforesaidinvention. Fig. 2 is a cross-section on the line 2 2, Fig. 1. Fig. 3 isan end view of the pin as seen from the right with reference to Fig. 1.Fig. 4- is a reverse side view of the guard end of the pin. Fig. 5 is aperspective view of the guard, and Fig. 6 is a view showing a suitableform of sheet-metal blank for the guard.

While my improved safety-pin is suitable for all the various uses towhich safety-pins may be applied, it is of special advantage andconvenience for fastening bandages in surgical cases, since it can beeasily and quickly closed and opened with the thumb and linger of onehand.

Referring to the drawings, the pin or point member a and the body or barmember 7) of the pin may be conveniently made in the usual way from asingle piece of suitable springwire bent to form a loop or coil 0 or anysuitable form of spring connection between the two members at one end ofthe pin. The free end of the body or bar member 6 is preferably benttoward the point of the pin for the attachment of the guard.

The blank for the guard, which is made of spring sheet metal, may be cutor stamped in substantially the form shown in Fig. 6. It

is composed of two main wings or parts (Z shown in Figs. 9. and 5.

and e, joined together at the ends by an intermediate part f, whichconstitutes the outer closed end of the guard, and the wings (Z and abeing free at their opposite ends are thus yicldingly held together. Thewing or part a is cutaway on one side, so that it is narrower than thewing d, which on the corresponding side has an extension 9 to be foldedaround the free end of the body member Z), as shown in Fig. 5, therebypermanently securing the guard to said member. If necessary ordesirable, the extension g may be slit transversely, as shown, tofacilitate folding it'over the curved portion of the member 7). On theiropposite sides the two wings or parts (i and e are formed withcorresponding lips lt, which preferably have curved margins ofapproximately the form shown. These lips are bent over in the samedirection approximately on the lines vi i, Fig. 6, to form twocorresponding inturned hooks or pockets on that side of the guardnearest the pin member a when the wings a and e are folded togetherapproximately on the transverse lines 7' j shown on Fig. 6. The wing cis bent lengthwise from its hook, lip, or pocket 72. toward the opposingface of the wing (Z, so that its edge opposite said lip or pocketnormally meets or lies close to the wing (Z, as To permit bending theinner edge of the wing 1 at its outer end against or close to the wing dand to allow it to yield more freely away from the opposing face of saidwing (Z, a transverse slit ll: may be made.

The interned lips or hooks it normally come together or close to eachother and form a converging opening through which the point of the pinis guided into the shield. The receptacle formed by the shield for thepoint of the pin is approximately heart-shaped in cross-section, asshown in Figs. 2 and 5, and the opposing faces of the wings (Z and 0converging toward both the longitudinal slits between them and towardthe body member 5 the point of the pin member a when pressed toward thebody member b is first guided into the shield through the outer slit,and if then released it will be caught and held in one of the hookedlips or pockets it. By pressing it farther toward the body member 6 thepoint will pass out of the shield through the inner slit, the wing espringing away from the wing (Z sufliciently to permit its passage andthen springing back, and thereby preventing the point of the pin whenreleased from reentering the shield in the opposite direction.

It will be observed that both in closing and opening the pin the pointis pressed toward the body member and that it cannot pass in theopposite directionthrough either of the longitudinal slits or openingsbetween the two wings (Z and c.

1 do not wish to be understood as limiting myself to the precise detailsof construction,

particularly with reference to the shield herein shown and described, asthey may be varied without materially afiecting the operation of the pinwithin the spirit and intended scope of the invention.

I claim-- 1. A safety-pin consisting of pin and body members having aspring connection at one end tending to separate the point from the bodymember, and a shield composed of two connected parts yieldinglyconnected together and shaped to form a receptacle for the point of thepin member and comprising walls one converging toward the other and thebody member and forming passages terminating in longitudinal slits oropenings through both of which the point of the pin can be pressedtoward the body member either into or out of the receptacle inrespectively fastening and unfastening the pin but not in the oppositedirection through said slits or openings, substantially as described.

2. A safety-pin consisting of pin and body members connected at one end,and a shield attached to the opposite end of the body member andcomposed of two connected parts yieldingly held together and forming areceptacle for the point of the pin, with walls converging toward thebar member and separated by expansible longitudinal slits or openings,which permit the point of the pin to be pressed toward the body membereither into or out of the shield in respectively fastening andunfastening the pin and prevent movement in the opposite direction,substantially as described.

3. A safety-pin consisting of pin and body members having at one end aspring connection with each other which tends to carry the point awayfrom the body member and a shield composed of wider and narrower partsor wings which are connected with each other at the outer end so as tobe yieldingly held together, and are bent lengthwise of the pin towardeach other and toward the body member, converging toward their edgeswhich normally lie close to each other on the side of the shield next tothe pin member, the opposite longitudinal edge of the narrower wingnormally approaching close to the opposing face of the wider wing whichis attached to the bar member, substantially as described.

4. A safety-pin comprising pin and body members having a springconnection at one end tending to separate them at the opposite end and ashield composed of two wings connected with each other at their outerends, one wing being wider than the other and attached to the free endof the bar member, the opposite edges of the two wings being bentinwardly toward each other and toward the body member and forming twohooks or pockets with an inwardly-converging opening between them forthe entrance of the point of the pin, and the narrower wing gradually approaching the other wing toward the body member and forming with saidwider wing a contracted opening or eXpansible slit for the eXit of thepoint of the pin from the shield, substantially as described.

5. A safety-pin comprising pin and body members having a springconnection with each other at one end, and a spring-metal shieldcomposed of narrower and wider wings bent longitudinally and foldedtransversely upon each other into a receptacle for the point of the pin,approximately heart-shaped in crosssection, with expansible longitudinalslits between the two wings for the entrance and exit of the pin-pointwhen pressed toward the body member into and out of said receptacle,substantially as described.

In witness whereof 1 hereto atfix my signature in presence of twowitnesses.
